You must build the altar of the Lord your God with whole stones and offer burnt offerings on it to the Lord your God.
As the temple was being built, only stones shaped at the quarry were used; the sound of hammers, pickaxes, or any other iron tool was not heard at the temple while it was being built.
If you make me an altar of stone, you must not build it of stones shaped with tools, for if you use your tool on it you have defiled it.
and live in love, just as Christ also loved us and gave himself for us, a sacrificial and fragrant offering to God.
Then you must build an altar there to the Lord your God, an altar of stones – do not use an iron tool on them.
Also you must offer fellowship offerings and eat them there, rejoicing before the Lord your God.
